b) If there are other radio control models in the vicinity, check with the operators that your radio 
is  not on the same  frequency. If  it  is,  make arrangements to run  your models at different times. 
This  step  does  not  apply  if  your  radio  is  on  the  2.4GHz  band  as  this  automatically  selects  an 
available frequency. 
c)  Turn  on  your  radio  and  check  that  it  is  operating  correctly;  carry  out  a  range  check  as 
explained in your radio instruction manual. 
d) Check that your Fail Safe is working correctly. 
e) Look around and ensure that the area where you will be operating the boat is clear and there 
are no people, other boats (models or full size) or debris in the water. 
f)  Study  the  area  where  you  plan  to  put  the  boat  in  the  water  and  check  that  there  are  no 
obstructions or weed, and that the water is deep enough. 
g) If other RC boats are running, especially if it is an RC Boat Club area, find out any rules about 
in which direction the boats run. In most cases, boats run in a clockwise circuit (ie turning to the 
right). Do not run your boat in a different direction to the others, and keep to any defined circuit. 
h) If other people are close by where you are starting your engine, make sure they keep clear of 
the boat ­ especially keep them well away from the prop. 
i) Review all the safety procedures mentioned at the start of this Manual. 
j) Make sure you have some method of retrieving your boat should it stop on the water for any 
reason. Never swim out to retrieve a boat. Some people have a small inflatable dinghy they use 
as a "rescue boat". If your lake or pond is not too big, you can use a tennis ball on a long length 
of  light  line.  Throw the  ball  over  the  stalled  boat  and  gently  pull  on  the  line  to  bring  back  the 
boat. If in doubt about rescue methods, check with your local RC Boat Club. 
*  Fill  the  gas  tank  and  start  the  engine  as  explained  earlier.  Wait  a  few  seconds  to  ensure  the 
engine is running correctly. Momentarily advance the throttle and check that the clutch engages 
to spin the prop. 
* Fit the engine hatch to the boat, ensuring the latches are secure. 
* Whilst  you can  launch the  boat yourself,  it is  best to have a  friend take the boat to the water 
while  you  hold  the  transmitter.  If  you  do  launch  yourself,  practice  first  without  the  engine 
running so you can safely put the boat in the water. It may be best to first put the transmitter in a 
safe spot near the water's edge before putting the boat in the water, rather than risk dropping  it 
while carrying both it and the boat. 
* When carrying the boat, always watch that nothing is close to the prop and that you keep clear 
of other people. 
* Gently place the boat in the water with the front pointing out into a clear area. 
*  If  other  RC  boats  are  running,  make  sure  they  are  well  clear  before  slowly  pulling  the 
transmitter trigger and accelerating your boat away from the shore. 
*  Allow  the  boat  to  rise  on  plane  but  keep  to  around  half  throttle  and  check  the  steering  by 
operating the rudder. 
* As soon as you can, whilst allowing for any other boats or circuit­keeping requirements, bring 
your boat back past where you are standing and check that water is flowing through both outlets. 
Get into the habit of checking for water flow every time the boat goes past. Weed or debris in the 
water can block pick­ups at any time and quickly cause overheating and damage to your engine. 
*  Enjoy  running  your  boat,  gradually  increasing  speeds  (but  remembering  to  properly  break­in 
the  engine)  and  becoming  familiar  with  how  your  boat  turns  and  handles  in  different  water
